In eukaryotes, DNA
Is located in the nucleus
Floats freely in the cytoplasm
Is located in the ribosomes
Is circular
The “backbone” of DNA is made of
Sugar and nitrogenous bases

Phosphate and lipids
If the enzyme helicase did not function properly, then
Hydrogen bonds between the new DNA strands could not form
New nucleotides could not be added to the new strand
The Okazaki fragments could not be linked together
The hydrogen bonds holding the two strands together could not be broken
When one DNA molecule is copied to make two new DNA molecules, the resulting DNA molecules contain
None of the parent DNA
50% of the parent DNA
75% of the parent DNA
100% of the parent DNA
Based on your answer from the question above, we call DNA replication
Conservative
Semiconservative
Semicomplementary
Complementary
One strand of DNA runs 5’-3’ while the other runs 3’-5’. Because of this, we say DNA strands are
Complementary
Antiparallel
Semiconservative
Leading and lagging strands
What is the first step of DNA replication?
1. Hydrogen bonds between nucleotides refor
2. Helicase breaks the hydrogen bonds between nucleotides.
3. Ligase binds together Okazaki fragments.
4. DNA polymerase adds nucleotides to the new DNA strand.
